If this truly a paid promo, then this isn’t a good sign…IMO, it would mean we are not close to approval since an approval should generate a share price grater than $1.
Why spend precious resources on something so short term?…Unless of coarse it is not short term and measures are taken place to keep share price from dropping further since we are about to see heavy dilution.
Disclosure: I sold over 300k shares October thru January (yes, for a loss) and still own 198k but will likely lighten up as the silence grows louder.
